(01. 123-122) This invention relates to a fuel charge heating vehicles, and has for its efiicient operation of a motor of the internal combustion type from a fuel 5 heavier and of less expansive power than that of gasoline thereby resulting 'fuel costs.

in a material saving of A further object of the invention is to provide,

in a manneras charge heating hereinafter set forth, a fuel means constructed and arranged for utilizing directly the exhaust from a' motor of the internal charge of the combustion type, prior to the disexhaust into the atmosphere to increase the expansive power of a fuel heavier than gasoline subse bustion space heavy fuel will of the motor at quently supplied to the comof the motor whereby the heated provide for the efiicient operation a material saving in fuel costs with respect to that of gasoline or other lighter fuels.

A further object of the invention is to provide, in a manner as hereinafter set forth, a fuel charge heating means arranged at and coacting with the intake and exhaust manifolds of heating a fuel charge heavier than to the supplying of space of the motor,

the motor for gasoline prior such fuel to the combustible whereby the expansive power of the heavier fuel is materially enhanced to provide for an eflicient operation of Further objects of the invention in a manner as hereinafter set forth,

the motor.

are to provide, a fuel charge heating means for the purpose referred to, which is comparatively simple in its construction and arrangement, strong, durable, compact, readily installed with respect to a motor or engine of the internal combustion type, thoroughly efficient in its use, and compar facture.

To the above en which may hereinafter sists of such parts,

atively inexpensive to manuds essentially and to others appear, the invention conand such combination of parts which fall within the scope of the invention as claimed.

of the said means.

The adaptation of a fuel charge heating means, :in accordance with this invention, is illustrated by way of example to be installed with an internal combustion motor of type.

the four cylinder The fuel charge heating means includes a closed housing I consisting of a series of detachably connected parts providing the bottom, top, sides,

front and rear there heat chamberA in of. The housing I forms a which is arranged the intake and exhaust manifolds E and S for the cylinders (not shown) of the motor (not shown). The

rear wall C of housing I is formed with openings X for the passage of holdfast devices to anchor housing I to the motor cylinders and also with openings X for the the manifolds. The intake manifoldE tical part E to be coupled with passage of the branches of has a veris adapted the carbureter (not shown) of the motor. The exhaust manifold S includes a tubular part S municates with closedto chamber'A munication with the which iscommon to and comthe exhaust of the motor. The said the cylinders of part S at. one end T is and is in permanent comexhaust of cylinder of the bank of cylinders. The other end of part S is closed as at T,

communication with outer motor cylinder The part S is formed with but is in permanent. the exhaust of the other of the bank of cylinders.

the discharge therefrom of the products of combustion from the cylinders directly into the chamber A to act upon the intake manifold E to heat the heavy fuel charg bustion chambers of e flowing towards the comthe motor cylinders for the purpose of increasing the expansive power of such fuel.

The direction of travel of the fuel charge is indicated by the arrows U. The directions of travel of the products of combustion from the motor cylinders are indicated by the arrows V.

The bottom B of housing I is formed below the closed end T with municates with a con the products of chamber A will an opening M which comducting off pipe S" whereby combustion supplied directly to be discharged from the latter,

but not before such products have acted to heat the intake manifold E to enhance the expansive power of the fuel charge which is supplied from the carbureter to the part E of the intake manifold.

As the front wall 3' connected in closure of housing I is detachably position, it may be readily.

which extends through and depends from the bottom B of housing I and one outer motor an opening 0 for I discharge disconnected so access may be had to the interior of chamber A.

As shown in Figure 1, the fuel charge heating means is shown as having attached therewith a humidifier device l-I leading fr om a water supply D and including afloat operated controlling element F. The intake manifold E is formed with an opening E" centrally of its top for the purpose of receiving the inner end of the humidifier device H whereby communication is'established between the latter and intake manifoldiE. (The use of the humidifier device H provides for the, combining of steam with the charge of 1 heavy fuel, thus increasing the expansive power of the fuel. The device H extends through'an opening H in one of the side walls B of housing If.

The manner of setting up the fuel charge heating means in the manner as referred to retards the discharge of the hot products of combustion supplied directly to chamber A which quickly raises the temperature in'the latter, whereby the heating of the charge of heavy fuel is had to the extent to materially enhance the expansive force of the charge resultinginan efficient operation of the motor at a lmaterially'le'ss expense than would be the case if the fuel charge employed 'was'gasoline'.
